Question Analysis
This question checks whether the student understands which numbers fall in the overlap of integers and whole numbers, but outside natural numbers.
The main focus is identifying the unique position of zero.

Key Concept Explanation
Integers: {..., –2, –1, 0, 1, 2, ...}
Whole numbers: {0, 1, 2, 3, ...}
Natural numbers: {1, 2, 3, ...}
→ So, only 0 is in both integers and whole numbers but not in natural numbers.

Step-by-Step Solution
A. {0, 1, 2} → Includes natural numbers → ❌
B. {–1, 0} → –1 is not a whole number → ❌
C. {1, 2, 3} → All are natura...
